4-6 Troubleshooting
Machine Run/Stop LED Green but Press Won’t Start
If the Machine Run/Stop LED is illuminated green, but you cannot start the press, check the
stop relays on the Relay board on the optional Shadow 8 control box Main board (see
Figure 2-20, page 2-32), following the instructions in Checking and Replacing Control Relays
in Optional Shadow 8 Control Box, page 4-9.
Every Other IBI Lit
When alternate IBIs on Main or Extension heads are illuminated, the minimum number of
consecutive beams that must be aligned is not being satisfied (see Table 2-13, page 2-50).
Correct the misalignment, then turn the Program/Run/Start key to START.
Transmitter Status LED Is Flashing
When the Transmitter Status LED indicator is flashing, it indicates that the transmitter ground
wire may not be connected to the ground stud within the Shadow 8 control box. Check the
ground wire connection and correct if necessary. If this does not solve the problem, return the
transmitter to Wintriss for repairs.
Machine Run/Stop and Blanking Active LEDs Flash Simultaneously
When the Machine Run/Stop LED flashes red and the Blanking Active LED flashes amber at
the same time, the number of beams you are attempting to program in a fixed blanking
window is preventing the required number of consecutive beams from remaining
unobstructed (see Table 3-1, page 3-6). Turn the Program/Run/Start key to START to clear
the error, then re-program the fixed blanking window, reducing the number of blanked beams.
Shadow 8 Control Box or WPC Power LED Dims and Blinks
If the Power LED on the Shadow 8 control box or WPC enclosure dims and blinks, a Receiver
or Transmitter segment has shorted the 24 volt power internally. To determine the source of
the problem, turn off power and unplug the Main Transmitter; then, turn the power back on. If
the Power LED still dims and blinks, a Receiver segment is defective. If the Power LED
behaves normally, a Transmitter is at fault.
GUARD AGAINST ELECTRIC SHOCK HAZARD
• Ensure that the power source is off before checking or replacing fuses.
• Turn off and disconnect power from the Shadow 8 safety light curtain and from the machinery it
is connected to, including the machine control and motor, before making any wiring
connections.
• Ensure that all procedures are performed by qualified personnel.
Failure to comply with these instructions could result in death or serious injury.
